OK, I've implemented symbolic arithmetic. I also implemented "n"
as an alias for numeric_approx. They are both in the attached patch,
which you can either apply (via hg_sage.apply('5302.patch') followed by
sage -br) -- or you can wait for SAGE-2.7, which will
(really) be released fairly soon (now that I'm back from vacation).
